Hello I had the same issue the take up reel tensions need to be adjusted try this thread tape so that there is no slack hold one of the tension guide reels try the right one first hold it so that it is in the 12 oclockpostion this is so that it wont retract to the left which will prevent the motor from stopping or going into the cut off position if it continues to play with you holding it in this position the the tension for the reels need adjusting this can be done by slightly turning the blue adjustment knobs that read PLAY / TU 7 FWD 10 one is for 7 inch reel and the other is for 10 inch reels it's the board at the very top of deck when you take the cover off turn them slightly to the left until problem is gone this is what I did and it worked

Hi Kip,
This is the typical service request and I do not have experience with that deck but many others in the last 40 years. I am still working on decks in the Chicago area if you need it looked at and there are guys allover the states that could also do it. You might post this on tapeheads.net forum where you would get more help and loactions of people near your area.

This is a matter of the safety switch microswitches and the tension arm rollers and lubrication needed. I have replaced these 30 year old microswitches in the past and had to deal with the shut off issue as well. To get to the parts you need to take the machine apart somewhat- front panels off and so on. I have had 9 of those here in the last year.If you want my help in the Chicago area- skywavebe @sbcglobal.net

Main code 2X : Mechanism control system error574 Failed to detect the T reel FG during search.

This means the take up reel stopped rotating during forward search. It shut down assuming tape was spooling loose into mechanism. Could be just a faulty cassette tape. A common problem is also when labels have been placed in the wrong places on the cassettes, stopping the lid from opening fully and stopping the reel reaching the reel motor drive.Manually eject the tape and try another tape. If the fault continues, have a look for something in the way under the cassette such as post it notes, paper clips, torn labels etc.Have you had the unit serviced since you got it?Could be time to get it to a service centre for help.

Jazzie: Your pinch rollers are worn. Put in a new set and probably a drive belt while you're at it and you'll be back in business. When the rollers are worn and tapered, the tape just rolls right off. Be sure to get the Pioneer replacements! Part---- RXB-325

This is a problem with the process called 'tape loading' - pulling the tape loop out of the cassette and wrapping it around the spinning video drum, engaging the capstan and pinch roller and reel rotation.
With the cover off, observe the behavior when you hit play. (You may need to put a piece of cardboard over the cassette to block external light from interfering with the start/end tape sensors). Assuming this is a basic VCR (no instant start features), you should see:
1. The video head drum begins to spin.
2. the roller guides move smoothly on the tracks, wind the tape around the drum, and stop snuggly pressed against the 'V-stopper' at the end of the tracks.
3. The pinch roller moves into position and presses the tape against the capstan.
4. The tape begins to move and is wound up by the takeup reel.
5. The picture and sound appear on the TV.
With a 'rapid or quick start' (or it may be called something else) transport, the tape moves to a half-loaded position when the cassette is inserted.
This is at an intermediate position partially pulled out of the cassette but not wrapped around the drum. On VCRs with a real-time counter and/or index search capabilities, the tape will be in contact with the control head.
With an 'instant start' transport, the tape will fully load around the spinning drum when the cassette is inserted but the capstan will not engage and no tension will be applied to the tape until you press PLAY or REC. (After about 5 minutes, the drum will stop and it may unload to the half loaded or unloaded position.)
Note that for VCRs with a real-time counter and/or index search capabilities, the tape must be in contact with the control head (but not the video heads) for all relevant modes. These VCRs (which include many modern units) must therefore pull the tape at least partly out of the cassette.
In all cases, the completion of the sequence results in approximately the same mechanical configuration during PLAY.
Several likely possibilities when it shuts down:
1. Everything occurs as above, picture and sound appear for a few seconds, but then the VCR unloads the tape, ejects the cassette, goes into REW mode, stops, or shuts off. Two common causes:
The takeup reel does not turn and tape spills into the machine. This is sensed by the microcontroller which aborts record or play and attempts to save your valuable cassette. Most likely cause: old/dirty idler tire. As a test, turn the idler tire inside-out. The fresh surface will now work well enough to confirm this diagnosis and will continue working long enough for your replacement idler tire to arrive. See the section:
"General guide to VCR cleaning and rubber parts replacement".
The takeup reel is turning properly but one of the reel
The takeup reel is turning properly but one of the reel rotation sensors or its electronics is defective. As a test, check to see if the tape counter is changing at any time during the loading and
